我正在使用Django Rest Framework。我定义了一个序列化器-没有模型的ReceiptLog，当对收据日志发出post（）请求时，应该在TestCaseCommandRun和TestCaseCommandRunResults中创建条目。收据日志在数据库中不存在，我只是将其用作端点来接受组合的有效负载并在基础表中创建条目。我不希望对ReceiptLog序列化程序执行get（）请求。
下面是代码段。
问题：
models.py
class TestCaseCommandRun(models.Model):
# fields
class Meta:
managed = False
db_table = 'test_case_command_run'
unique_together = (('team_name', 'suite_name', 'suite_run_id', 'case_name', 'command_name'),)
class TestCaseCommandRunResults(models.Model):
# fields
class Meta:
managed = False
db_table = 'test_case_command_run_results'
unique_together = (('suite_run_id', 'command_run_id', 'rule_name', 'result_id'),)

我们非常感谢您的帮助。

DRF中的视图非常模块化，您可以选择仅使用所需的HTTP方法。对于您而言，最好的选择是使用CreateAPIView。
from rest_framework.generics import CreateAPIView
class ReceiptLogView(CreateAPIView):
serializer_class = serializers.ReceiptLog
这还将确保使用GET或其他方法时，即使在可浏览的API中，也将返回不允许的405方法
我真的不理解您的第二个问题，因为视图（和视图集）和序列化器具有不同的用途，并且不易混淆。
我也建议您改善命名。序列化程序名称应以Serializer结尾，以免将它们与模型混淆。

我更新了urls.py以包含以下行
url(r'^dqf_api/ReceiptLog/', views.ReceiptLogView.ReceiptLogViewSet.as_view(), name='ReceiptLog')
